Vibration isolators spring type MSN-BL and DMSM-BL

Manufacturer: Getzner Spring Solutions

wibroizolator blokowy MSN-DMSN-BL Getzner

The Isotop® MSN-BL and Isotop® DMSN-BL block vibration isolators are designet for low installation heights and high loads.


Block vibration isolators Isotop® MSN-BL and Isotop® DMSN-BL consist of two steel plates with spring elements (vibro-isolators) installed between them. There are 4, 6 or 9 elements for MSN-BL and 16 elements for DMSN-BL, depending on the load. Respectively: series MSN 5/KTL to MSN 8/KTL and series DMSN 6 to DMSN 8. Special versions are also available on request. 

Block vibro-isolators are highly resistant to corrosion, as the spring elements are protected by cataphoretic painting (CDC), and the plates by powder coating.


The Isotop® MSN-BL block vibration isolators have a natural  frequency from 3,5 Hz, and Isotop® DMSN-BL from 5,3 Hz.
They are used for fixing equipment to the foundations: 

  • Compressors,  
  • Ventilators,
  • Air conditioners,
  • Speakers,
  • Sensitive electronics,
  • Measurement instruments and scales,
  • Control cabinets,
  • Pumps,
  • Emergency power generators,
  • Other machines and devices, especially ones with low vibration frequency.
    Isotop® DMSN-BL are recommended especially for machines that frequent starts and stops.
